I should have cleared out the letters years ago

The standout episode of this, and possibly any, series of the dystopian and occasionally apocalyptic sci-fi show Black Mirror, is Eulogy.

- 

In it, a grumpy middle-aged man, played to absolute perfection by Paul Giamatti, trawls through old photographs of a former girlfriend from the late 80s and early 90s to digitally harvest his memories of their relationship for her family to play at her funeral, with the aid of what looks like a glow-in-the-dark Trebor mint stuck on his temple that makes his eyes frost over when it's on.

So far, so typically nightmarish of a series that's now become a byword for a world that's rapidly gone to the dogs. In fact, you could wrap up most TV news bulletins of the last 10 years with a credit sequence that ends with “Written by Charlie Brooker”.
